Like Howard I am a CET and in the day when I was learning, the
programs actively discouraged people with problems like colour
blindness.<br>
Almost all the courses were technical or math related and no thought
was given to human factors or access for people with impairments.<br>
I would hope that things are a bit better now.<br>
<br>
I know that you can get the ring back on by feel having done the
same kind of thing many times working on objects that are not
visible while being worked on.<br>
<br>
Products like locktite or Krazy glue will require a reasonable level
of eye-hand co-ordination and may be beyond what your vision will
allow.<br>
<br>
In essence what you are trying to do is stop the ring from spinning
off.<br>
This can be done by inserting something into the threads while the
parts are being assembled or by applying some glue like substance
that will bind the ring to the surrounding surface.<br>
<br>
The problem with the various solutions to this point are that they
require knowing how much product you get on the parts and being able
to assemble them while touching almost nothing of the parts being
assembled.<br>
<br>
If you go to a local hardware store or Home Depot I am sure the
staff would be willing to glue the part in place for no charge if
you buy the product.<br>
This is a fix that should only take seconds to a few minutes and is
not technically demanding.<br>
Of course this would require you to drag your scanner out to the
local hardware store or Home Depot.<br>

Explain how you would tell these apart if blind?
<br>
What does your engineering background, since you reference here,
teach you about working via touch alone?
<br>
That is my situation here. I must be able to safely apply this,
without seeing its shade onto an extremely small space.
<br>
Or, I can take this scanner and this ring to a business and pay
someone to replace the ring.
<br>
if so, where?

Ask about threadlockers in the hardware store. The really
popular one is Loctite 242, which is a lubricating, medium
strength threadlocker which is blue in colour. This is very
nice stuff for mechanical assembly. The lubrication gives you
better control over tightening torque, which is really cool if
you are using a torque wrench. :) Alternate threadlockers can
be sealing or wicking. Wicking might be very nice for you, but
you probably won't find this stuff in a regular store. Most
threadlockers are based on Military Standard MIL-S-46163A, and
several manufacturers make equivalent, compliant stuff. The
colours are part of the standard. Purple is low strength, blue
is medium, and red is high strength. The blue, medium strength
is good. The red, high strength is difficult to remove without
damaging things.
<br>
<br>
The regular Loctite threadlockers can be very nasty around
plastic electronics like connectors and PCB components. Be
very, very careful to apply it only to metal components. I have
had some nasty experiences with this.
<br>
<br>
Consider usng Krazy glue, and wicking it into the thread. If
you don't glue your fingers together, you should be fine. Look
for a thin cyanoacrylate glue. The thick, goopy stuff won't
wick.

Will seek it at walmart or Home depot.

I even have more than one.
<br>
so you put this liquid on the ring and it sticks in
place?
<br>
Where do I get this product?

Typically hardware stores, etc.. Walmart has it.
